Windows上的回形针-nil:NilClass的未定义方法"split" [英] Paperclip on Windows - undefined method `split' for nil:NilClass

问题描述

当我尝试保存上传的文件时，我得到了nil:NilClass的未定义方法'split'

I am getting undefined method `split' for nil:NilClass when I am trying to save uploaded file

@user.avatar=params[:user][:avatar]

这是服务器日志中的错误:

Here is the error from server log:

我猜想问题在于文件名太长(C:/progs/web/ror_site_1/tmp/Rus220120701-4976-1sky1nn20120701-4976-a9j1sh20120701-4976-tm6qoj)并且无法在Windows中读取.如果是这样，如何更改文件名生成规则?

I guess the problem in that the filename is too long (C:/progs/web/ror_site_1/tmp/Rus220120701-4976-1sky1nn20120701-4976-a9j1sh20120701-4976-tm6qoj) and cannot be read in Windows. If that is true, how to change filename generation rules?

如果不是，那是问题的原因吗?

If not, that is the reason for the issue?

推荐答案

这是几个最新版本的回形针存在的问题(解释).我也遇到了这个问题，直到我将回形针设置回3.0.4版本后，它才再次起作用.

This is a problem with the few latest releases of paperclip (explained here).I also had this problem, and it wasn't until I set paperclip back to version 3.0.4 that it worked again.

因此，只需将其放入您的Gemfile中，直到修复程序发布为止:

So just put this in your Gemfile until the fix is released:

gem 'paperclip', '3.0.4'
